'HOT-WATER -H EATING SY-S-TEM.

SPECIFICATION forming part of ietterslliatent No. 741,070, dated October 13, 1903.

Application filed July 18, 1899. Serial No. 724,233. (No model.)

To all whom, it may concern: 7

Be it known that I, ANDERS BOROH BECK,

a subject of the King of Denmark, and a resident of Copenhagen, Denmark,have invented certain new and useful Improvements in Hot- Water Heating Systems, of which the following is a specification.

This invention relates to hot-water heatin g systems worked by steam, especially 1 w: pressure steam; and the object of the'inv'ention is to create means for attaining that by only changing the load on the pressure-regulator that controls the pressure of the steam, the hot-water system can be worked in two distinctly diiferent manners, one for low and the other for high temperature on the water.

In order that the invention may be more readily understood, I have appended hereto a drawing diagrammatically illustrative of an installation in which water-heaters are shown as arranged on three floors of a building.

In the said drawing, 1 is a steam-boiler heated by the furnace 2 and provided with a pressure-regulator 3, which serves to regulate the draft to the furnace by opening and closing to a greater or less extent'the dampervalve 4, leading to the ash-pit 5.

6 is the water heater, designed to supply hot water to the heaters. Thewater in said heater 6 is heated by the. steam-pipe 7, by which steam is led from the steam-space of the steam-boiler 1, thewater condensing i11 the said pipe 7 beingjreturnedto the steamboiler, as will be well understood. From the top of the watenheater 6 extends the vertical pipe 10, leading to. the separator 11,which will be hereinafter mentioned. Upon said pipe 10 and a few feet below the separator 11 is situated a steam heating mixing-chamber 12,

fed by steam from the steamspace of the .14 into the separator, where it is separated and condensed.

chamber.

tors 17, from which the water returns by the return-pipes 18 to the heater 6. a

19 is an overflow-pipe by means of which the superfluous 0r overflow Water from the separator 11 is led back to the water-space of the steam-boiler 1.

The pressure=regulator acts in the wellknown manner, the furnace-draft being diminished by increase of steam-pressure in the boiler.i

The apparatus works in the following way: When only little heatis needed in the building in which the apparatus is installed, the pres sure of the steam is kept at or-very near at- .column from the mixing-chamber 12 to the water-line in separator 11. Then steam will force its way into the water in the mixing- The'water will be heated here to the very temperature of the steam, and the admixture of steam-bubbles to the water in the short tube 14 between the mixing-chamber and the separator Will produce a strong circulation through the whole apparatus.

From what has been said it willbe seen that the whole system can be worked in two distinctly different manners by'only keeping the pressure of the steam either low or high. By low pressure the steam cannot force its way into the mixing-chamber 12, but only condenses in the pipes 7 of the heater 6. It then the condensing-surfaces of the pipes 7 are correctly proportioned, the water will only be heated to a moderate temperature in the heater 6, and as in this case the heater is the only place where heat is imparted to the Water the temperature in all hot-water pipes and radiators can only be low. On theother hand, if the pressure of the steam is kept sufficiently high the steam will be able to force its way into the mixing-chamber 12, the temperature of the water leaving the separator 11 through the main 15 will be just as high as the temperature of the steam, and by the action of the steam-bubbles rising in pipe 14 the velocity of the Water will be threefourths times as great as in the former case.

1 only here claim as newa system that has this feature: that a heater 6 and a mixingchamber 12 on the main rising pipe of the hot-water system are combined in such a man ner that by low pressure of the steam heat is only imparted to the water in the heater, Whereas by higher pressure a change is made quite automatically, by which heat is imparted to the water as well in the mixing-chamber as in the heater.

It is not necessary to have a separate steamboiler for each hot-water heating apparatus; but in such cases where several hot-water apparatus are to be worked from the same boiler the system is only altered in that manner that acommon steam-main supplies steam to all the hot-water apparatus and the pressure-regulator 3 controls a valve on the branch pipe from the steam-main instead of a valve in the air-supply pipe of the furnace of the boiler, as shown at 4 in the drawing.

Having thus described myinvention, What I claim as new, and desire to secure by Letters Patent, is v 1. A heating system including a boiler, a heater 6 adjacent to said boiler, a pipe 7 leading from the boiler through the heater and having a return, and provided with a valve 7 a continuously-circulating system associated with the heater, a separating-chamber 11 in said system, a heating and mixing chamber 12 in the outgoing pipe of the system and between the chamber 11 and heater 6, a supply-pipe 13 between the boiler and chamber 12 and having communication with the pipe 7 and a return-pipe 19 extending from the upper portion of the chamber 11 back to the boiler, substantially as described.

2. The heating system including a boiler, a heater 6 adjacent to said boiler, a pipe 7 leading from the boiler through the heater, and having a return and provided with a valve 7 a continuously-circulating system associated with the heater, a separatingchamber 11 in said system, a heating and mixing chamber 12 in the outgoing pipe of the system'and between the chamber 11 and heater 6, and a supply-pipe 13 between the boiler and chamber 12 and connected to the pipe 7. I

3. A heating system including a boiler, a heater 6 adjacent to said boiler, a pipe leading from the boiler through the heater, a continuously-circulating system associated with the heater, a separating-chamber 11 in said system, a heating and mixing chamber 12 in the outgoing pipe of the system and between the chamber 11 and heater 6 and a supplypipe 13 between the boiler and chamber 12 and connected with the pipe 7.

at. A heating system including a boiler, a heater 6 adjacent to said boiler, a pipe leading from the boiler through the heater, a con tinuously-circulating system associated with the heater, a separating-chamber 11 in said system, a heating and mixing chamber 12 in the outgoing pipe of the system and between the chamber 11 and heater 6, a supply-pipe 13 between the boiler and chamber 12 and connected with the pipev 7, and means for regulating the steam.

5. A heating system including a boiler, a heater adjacent to said boiler, a pipe 7 leading from the boiler through the heater, a continuously-circulating system associated with the heater, a separating-chamber in said system, a heating and mixing chamber in the outgoing pipe of the system and between the separating-chamber and the heater, said mixing and heating chamber including the two spaces'and a perforated partition separating the same, and a supply-pipe between said chamber and the boiler and connected with the pipe 7.

In witness whereof I have hereunto set my hand in presence of two witnesses.
